ROLLER-SKATE.

SPECIFICATION forming part of Letters Patent No. 616,773, dated December27, 1898. Application filed November 26,1897. sam no. 659,808. (nmina To all whom t may concern:

Be it known that I, TAYLOR E. DANIELS, a citizen of the U-nited States, residing at Ohicago, in the county of Cook and kState-of `Illinois, have invented a new and usefullmprovement in Roller-Skates, of which the following is a specification.v

The object of my invention is'to provide a generally improved but simple construction of roller-skate or footfcycle whereby it shall be rendered peculiarly light, strong, easy-running, and speedy and readily interchangeable from two front wheels to one front wheel, and vice Versa, whereby the spring action for controlling the steering by turning the front roller or rollers shall be adaptable to the Arequirements of users ofldifferent weights and whereby the wheel, with its l structure reduced to the fewest possible number of parts consistent with its roller-bearing character and its purpose, shall be rendered peculiarly durable and noiseless.

'- Referring to the accompanying drawings,

Figure 1 shows my improved roller-skate by a view in side elevation. Fig."2 is a top plan view ofthe same with the rollers omitted; Fig. 3, a section taken at the line 3 on Fig. l2, viewed in the 4direction of the arrowand enlarged; Fig. 4, a section taken at the line 4 on Fig. 3 and viewed in the direction of the arrow; Fig. 5, a section taken at the line 5 on Fig. 3.and viewed in the direction of the arrow 5 Fig. 6, a section taken at the line 6 on Fig..3 and viewed in the direction of the arrow; Fig. 7, a perspective view of a combined sleeve and washer detail;` Fig. 8, a section.

takenat the line 8 on Fig. 2 and viewed in the direction of the arrow; Fig. 9, a view in elevation of the spring; Fig. 10, a view in side elevation of the single front wheel and its means of connection with the skate, and

Fig. 11 a sectiontaken at the line 11 on Fig. 10 and viewed -in the direction of the arrow. A is the toe portion, formed as light as possible,` being .preferably cast of steel, in'

the shape illustrated.- The toe-portion is equipped, in suitable position, with the adjustable sole-clamps r fr, which may be of the common variety illustrated, whereby they are adapted to slide transversely of the toe portion, and carry on their under sides pendnationbaokward and downward (sayat an inclination of about' forty-live degrees) a its upper end a. transverse diaphragm p,' Fig. 3, having a` central opening p', aording a bearing, and containing also, in alinement with each other' and projecting inward' from its'wall, a lug o adjacent to the diaphragm and a lug o' Aadjacent to an annular odset o2 formed about the inner side of the housing, near its outer end.

phragm and is held, as `by a nut p2, (accessibley through the opening shown in Fig. 2 to be provided about the center" of the toe-piece,) to extend lengthwise through the center of the housing, and the stem 'carries near its its Outer end a disk-shaped head n, adapted to seat against the odset lo2 and aording on its outer side a cup for the balls q of a ba1lbearing deviceof usual or any suitable general construction, the lcone n 4of which is. ,screwed upon the outerv reduced end of the stem A2, in which position it may be locked against turning on the stem by a pin Inside the housing A' and abutting against the diaphragm therein is loosely confined about the-stema combined sleeve and washer device B, comprising a sleeve fm., having the offset m', and provided with an annular head or washer1 m2, containing a segmental recess m8 in its vedge and an opening m4 oppositethe recess. A device B', similar in form and con struction to the device B, is loosely adjusted about the stem A2 near its outer end, as shown in Fig. 3. The parts m of the two devices B and B' abut, while between the oset's m' through which there projects from the stem A2 a lug o to engage, by turning the stem, with either edge ofthe aforesaid recess, for a purpose hereinafter described. The lugs o:

and o' are embraced, respectively, bythe recesses mi in the annular heads of the `devices B and B', and in the housing about the ad- 'jacent sleeves mot' these two devices is confined a coiled spring 132havingit-s ends turned outward in alinement with each other, as shown at m5 mi' in Fig. .9, and respectively inserted into the openings m4 of the washers In adjusting this spring to insert its ends into the openings m4 it is set or flexed by slightly straining the coil backward at its ends in 'opposite directions-that is, in thedirection of uncoiling it.4 About the head n is fastened (as by screwing with a screw o" or pin. inserted to prevent independent rotation) a`ring C, having an axle-bearing C' extending from it for the lfront axle C2. the formof that represented-most clearly in Figs. 4 and 6 for use withthe skate when .two front wheels .D are employed, one on each end. of the axle, with the bearing be'- tween them, or it may be in thelyoke form most clearly represented in Fig. l1 for use where a singleffront wheelD is employed, in which latter formait supports the axle end and embraces the wheel.,`

The construction renders exchanging single and double frontwheels one for the other` a matter of ease, since to 'eiectithe changeit is only necessary .on 'unscrewing the nut p2 to withdraw from the skatel the stein A2 and parts it carries, as shown by Fig. 10, and sub'- stitute therefor the stem of the other wheeled device desired, meantime readjusting the spring B2 and devices B and B'.

The diameter of the rear wheel D' is by preference materially greater than that of the front wheel or wheels, thereby to increase the speed of the skate accordingly.

Each of the V)wheels may involve the same construction, which 'ls preferably the follow- This bearing may be in' at each ing and of the ball-bearing variety:l F is a sleeve having internal annular oifset's t and t' (see Fig. 11) formed at opposite sides of 'its circumferential center about its interior and affording abutments for the cups k 7a of the ball-bearing devices, the ballsv k of which are confined in place in a usual or any suitable manner, as by the cones'cf. About the sleeve is provided the tire lseat or rimshownl as formedof an internallyfshouldered flange t',

extending about `the sleeve at one-side of y its circumferential center and integral therewhereby a solid bearing is afforded to it, the

tire being formed as to its body portion of hard material; preferably, very hard rubber. To protect the material forming the body of the tire against fracture and at the same time to vrender the wheel noiseless, or comparatively so, an annular recess g, Fig. 4, is formed 'about f .the tread portion, and inV this recess Iwind andthus fill it to form the tread any suitable thread-like material G', preferably stout linen braid or twine preparatori] y soaked .in rubber -solution and dried.

H is a reach 'for separably connecting the wheelportion E with the toe portion A. It"

in the base of the toe portion A to extend' lengthwise thereof, thereach being firmly' held in any position to which it is adjusted' by a clam p-bolt s'. On loosening the bolt s' v the reach may be extended 'or contracted vto adjust the length of .the skate according to requirement, and on'withdrawin g the bolt the reach 'may be pulled away entirely to sepa' 111.5. irate the heel portion of the skate from the'toe 4 portion, andi thus'permit the latter to be used alone, as forV fancy skating.

What I claim as new, anddesire to secure by Letters Patent, is-

'-'1. In a roller-skate, the combination with 4the toe portion of` astem carryingthe frontaxle bearing and supported to rotate on its axis by turning the vfront wheel or wheels, a spring" controlling the rotation of said stem, and means for confining said spring and for ad j usting the tension thereof, substantially as described; 1 v l l 2.
